FOCUS: LATIN AMERICA • All the Villas-Boas brothers wanted was to get out of their small Brazilian town. So the trio—charismatic Claudio, devil-may-care Leonardo and levelheaded Orlando—signs up for the country’s 1943 “march west” into the jungles surrounding the Xingu River, ready to pave the way for urban expansion. What they find are indigenous tribes who will be displaced once their homeland is bulldozed away. Over the ensuing decades, the brothers will be the natives’ only protection from extinction, a process culminating in the creation of South America’s largest national park. Brazilian director Cao Hamburger, turning 180 degrees from his 2007 coming-of-age drama The Year My Parents Went on Vacation, delivers an epic biopic on Brazil’s environmental heroes, complete with an expansive scope and lush landscapes that would make David Lean envious. At the same time, he’s retained his previous feature’s sense of intimacy and humanism, and the result is a history lesson that appeals equally to the eye and the heart.
